Влияние лазерного излучения на проницаемость дентина и функциональное состояние пульпы препарированных зубов

Abstract

The use of fixed prosthesis without preventive measures to improve the resistance of the prepared teeth is unjustified from the biological point of view. The success of prosthetic treatment of the patients with non-removable prosthesis is largely determined by a therapeutic effect on the fabric of the prepared teeth and high-quality prosthetic fixation. One of the most promising ways to solve this problem is the use of laser radiation. Investigation of laser radiation effect on the permeability of dentin and pulp of the functional state of the prepared teeth consisted of experimental and clinical stages. Experiments were carried out on 16 vital teeth of two mongrel dogs. In the experiment the influence of DO on the permeability of the dentin the prepared teeth was studied by means of the microscope. The materials for the clinical study were the results of the orthopedic treatment of 105 patients aged 21 to 60 years (55 men and 50 women). To assess the state of reactivity of the teeth and the impact of treatment measures the authors used a study of temperature, tactile sensitivity, electro-odontometry by means of the device Digitest. The study demonstrated that the use of laser radiation significantly reduces the permeability of dentin prepared teeth. The use of laser radiation reduces the permeability of 40.9% compared with the control, significantly reduced the incidence of adverse results of applying non-removable dentures.
